Answer Posted / vignesh1988i

good morning sir,

in ur above program , u said u took then length as 8 and
then allocated ur memory using DMA... but ur way of
allocation find to be wrong sir.... as you allocated

int *ptr=(int*)malloc(sizeof(8));

the above statement will allocate only 2 bytes for u....
since you have given 8 inside sizeof operator.. this will
tell the compiler allocate 2 bytes of memory .. ur
instruction must be :

int *ptr=(int*)malloc(8*sizeof(int));

so, then it will allocate 8*2 bytes of memory sir.....

so only in my program i have given n*sizeof(int) , where
'n' can be any value that user gives........


thank u
